Yes, in the seals around the bearings, in any suspension element you might have, by the brake pads and so on.
Sliding Friction
Friction is increased on a bike saddle to help prevent the rider from sliding around or slipping off while pedaling. This can improve stability and comfort during the ride by providing better grip and support for the rider's body weight.
Roller Coasters. roller coasters are affected by rolling friction (hence roller) not sliding
You would experience fluid friction and rolling friction, and since you are not likely to be completely submerged, air resistance.
When you ride a bike through a puddle, you experience both kinetic friction between your tires and the wet surface of the puddle, as well as fluid friction from the water resisting the movement of your tires. The water can also create hydroplaning, reducing the traction between your tires and the ground.
You can ride up it using the Mach bike.
When riding a bike over cement, two main types of friction are present: static friction and kinetic friction. Static friction prevents the tires from slipping when you start moving or when you come to a stop. Once in motion, kinetic friction acts between the bike tires and the cement surface, opposing the bike's motion and affecting speed and control. Additionally, rolling friction occurs as the tires roll over the surface, which is generally less than kinetic friction.
Because when we ridind the bike faster to slow down the brake is important
A bike can be difficult to ride if it needs oiling because the lack of lubrication in the chain and moving parts causes increased friction. This friction makes pedaling harder and can lead to stiff or unresponsive gears. Additionally, rust or dirt buildup can occur without proper lubrication, further hindering performance and making the ride less smooth and enjoyable. Regular oiling ensures that parts move freely and efficiently, enhancing overall ride quality.
Centripetal force, friction, and gravity are the main forces that keep you in place on a fairground ride. Centripetal force pulls you towards the center of the ride, while friction between your body and the seat helps prevent you from sliding. Gravity also plays a role in keeping you grounded and pressed against the ride.
Bike pedals squeak when you ride due to friction between moving parts, lack of lubrication, or loose components. Regular maintenance and proper lubrication can help reduce or eliminate the squeaking noise.
i think you need the most friction in your feet and handsIt's hard to say where you'd need the mostfriction, as riding a bike requires several thingsto work together. And in each of those places you need enough friction.-you can't ride if tires will slip too badly on the ride surface-you can't ride if tires will slip too badly on the rims-you can't ride if wheels won't stay in the frame/fork-you can't ride if you can't stay on the bike
